Please explain why you selected the houses you did in Q1 and Q2. Please include what types of hazardous phenomena (e.g., liquefaction, tsunami, landslide, etc.)

you would expect at the other two houses you didn't select in Q1 and Q2 that would make it an earthquake hazard and WHY.
What will be an ideal response?

Answer to Question 1

C is at lowest risk: sits on granite (solid rock), above water table (no worries about liquefaction), and the slope to the right of the house is at a stable angle (not too steep), no houses above it that would fall onto it.
B is at highest risk: sits on the fault, which will most likely shift and tear the house apart; close to the water table, so liquefaction is a problem.
D is modestly stable and it is above the water table so no real risk of liquefaction.
A is close to the water table and on recent, unconsolidated sedimentary deposits, which will most likely suffer the effects of liquefaction. A could also slide down into the ocean, as it sits on the block that is going down. It will NOT suffer from a tsunami because the fault is not under the seafloor; however if the vertical motion on the fault is large enough, location A could be partly submerged as it subsides below sea level.

Answer to Question 2

B
